u-boot skips all the block. This is not correct.

'nand erase' is supposed to skip all bad blocks. that is correct.
--- Yi Li 2009-03-27 02:54:19
When running "flash_eraseall" in kernel on the same board, there is no
bad block. Is u-boot and kernel use different method to mark bad block? If so,
this may need to be documented in wiki.
--- Mike Frysinger 2009-03-27 11:51:03
the kernel and u-boot use the same exact mtd layer. u-boot just rips it out of
the kernel and modifies it for its own use. so the OOB layout is exactly the
same. the only way it'd differ is if you select the BootROM OOB layout, but
that is already documented in that you need both u-boot and the kernel to use

After scrub, erase is OK. Bug can't write properly.

Use U-Boot 2008.10-svn1805 (ADI-2009R1-pre) (Apr 7 2009 - 15:38:05), nand
operation, erase, scrub, and write.yaffs are all successful.

This need to be marked as "fixed", not "out of date", isn't
--- Yi Li 2009-04-13 22:38:04
fixed and close.
